Abstract

The invention relates to an oil saturation determination method and device, electronic equipment and a storage medium. The oil saturation determination method comprises the following steps: a preset shale oil-gas saturation model and measurement parameters of the shale oil-gas saturation model are obtained; and the oil saturation is determined based on the measurement parameters and the shale oil-gas saturation model. The method can determine the oil-gas saturation of the shale.

Description

technical field [0001] The present disclosure relates to the technical field of petroleum and natural gas exploration and development, and in particular to a method and device for determining oil saturation, electronic equipment and a storage medium. Background technique [0002] In the current exploration and development of Daqing Oilfield, the shale oil and gas field has gradually become an important field for oil and gas replacement. Due to the complex framework minerals, complex pore structure, and pore wettability of this type of reservoir, this type of reservoir rock The electrical relationship is complex, non-Archie phenomena appear in the reservoir, and the relationship between water saturation and resistivity is no longer the only corresponding relationship. Factors such as shale content, pore structure, and wettability will all affect water saturation. Thus making the Archie saturation model no longer applicable. The evaluation of oil and gas saturation is the key...
